235859d66c Early CFG simplification can fold conditionals down to selects, which is often a good thing, but it can also
hide jump threading opportunities by turning control flow into data flow.  Run an early JumpThreading pass
(adds approximately an additional 1% to optimization time on SPEC), allowing it to get a shot at these cases
first.  Fixes <rdar://problem/8447345>.

36c4debc94 Fix PR8247: JumpThreading can cause a block to become unreachable while still having predecessor, if it is part of a self-loop.
Because of this, we cannot use the Simplify* APIs, as they can assert-fail on unreachable code.  Since it's not easy to determine
if a given threading will cause a block to become unreachable, simply defer simplifying simplification to later InstCombine and/or
DCE passes.

828916203a Add specializations of addrmode2 that allow differentiating those forms
which require the use of the shifter-operand. This will be used to split
the ldr/str instructions such that those versions needing the shifter operand
can get a different scheduling itenerary, as in some cases, the use of the
shifter can cause different scheduling than the simpler forms.

69c4cbe9e8 lit: Fix a subtle resource usage bug when executing tests using the internal
shell runner.

We would inadvertently end up holding on to handles to the temporary files
longer than we should have been. On Win32, where open handles lock some file
operations, this caused problems in tests which would try to move temporary
files around (as Clang does by default now).

Many thanks to Francois Pichet for the excellent detective work on this.
